Business has started to pick up as we approach the late September, early October released window of Windows 10 Fall Creators Update, and it is showing in the preview builds Microsoft pushes out.

The software titan will be sending these test versions out at a faster clip.

It has just released a new batch of builds for users keen on testing out the new features that are to be part of the platform. These come about just a week after the last one, and the version numbers you are looking for are build 16257 for PCs and build 15237 for smartphones.

Dona Sarkar, the head of the Windows Insider Program let the world know of this:

You can download this new mobile build by checking Windows Update on your phone, while PC users should also receive an update notification, as long as they have their device enrolled in the Fast ring of the preview program.

In addition to these two releases, Redmond has also made Windows 10 build 16251 available for Slow ring users, signaling that that particular version is now in a much more stable state.

As always, all these new versions bring along a number of new features, to go with a whole wall of bug fixes, but future preview releases will probably have fewer front facing additions, as we inch closer to the launch of the Fall Creators Update.
